I think I commented about this one in the database, but C4F (Chief Four Fingers) has had a low poly rate for me. I think one year it had two polys, a four-petal and a five-petal. The 5-petal poly was pretty impressive. So far, the plant hasn't had any spectacular traits, but it is pretty enough and I consider it a keeper. I doubt it will ever make my list of top favorites, but not every daylily can.
I believe I have been able to successfully pollenize with it as well as set pods in it, but no noteworthy characteristics on pollination or podding rates that I recall. If anything, maybe a little below average, but I would have to double check my records.
Now, to be fair, C4F has never been 'settled in' in my garden, and won't be for a few more years, I'm sure. I'll be re-planting it this year (if it survived the winter in it's pot). It might be a far more distinguished and noteworthy plant once settled.
(I'm zone 5b or 6a, depending what graph you go off of.)
